Decompose an origin footprint by the area and item of the product supplied to final demand. This adds the missing FABIO-viewer style phase between origin product and final-demand area: origin product -> supplied product area -> supplied product -> final-demand area.
Unlike compute_footprint_paths(), this does not show the first direct
intermediate input. It shows the downstream product row in Y whose final
demand carries the origin footprint.
Usage
compute_fp_product_paths(
z_mat,
x_vec,
y_mat,
extensions,
labels,
fd_labels,
origin_area = NULL,
origin_item = NULL,
output_tol = 1e-08,
value_added_floor = 0.001,
conserve_extensions = TRUE,
min_value = 0
)Arguments
- z_mat
Inter-industry flow matrix from
build_io_model().- x_vec
Numeric vector of total output per sector.
- y_mat
Final demand matrix from
build_io_model().- extensions
Numeric vector of environmental extensions per sector.
- labels
Tibble with
area_codeanditem_cbs_codemapping sectors.- fd_labels
Tibble labelling Y columns, from
build_io_model().- origin_area
Optional area code vector limiting origin sectors.
- origin_item
Optional item code vector limiting origin sectors.
- output_tol
Minimum output considered valid when computing extension intensities.
- value_added_floor
Minimum non-intermediate leakage share used when constructing technical coefficients from
z_mat.- conserve_extensions
If
TRUE, rescale positive paths within each origin area/item so their sum does not exceed the corresponding positive extension total.- min_value
Drop paths with values less than or equal to this value before returning.
